Abstract
本公开提出一种OAM波束传输方法的确定方法、装置、用户设备及存储介质，属于通信技术领域。该方法包括：向接收端发送参考信号RS；接收所述接收端基于所述RS反馈的信息；基于所述信息确定所述发送端对应的权向量，所述权向量用于调整发送端的发送阵列所发送的OAM波束的发散角；确定待发送OAM信号，并基于所述权向量调整所述待发送OAM信号的发散角得到调整后的OAM波束；发送所述调整后的OAM波束。由此可知，本公开实施例提供的OAM波束传输方法确保了OAM波束的接收质量，有效解决了共轴、移动场景下因模态及收发天线阵列的距离变化造成的OAM波束传输性能下降问题，提高了OAM波束的传输性能。
